Abstract
The utility model relates to a novel safe low-arc plug which overcomes drawbacks of electric plug in prior art to make arc generation time smaller than or equal to 1. The electric plug in prior art has two electrodes of same length in touch with two contacts of the socket in the same time, thus the two contacts generates arc in sequence, and inserting time is prolonged. Arc generation time may be greater than or equal to 2 times, which has high damage degree to the electric appliance. The product comprises a contact connected to the holding portion, an elastic device assembled on one side of the contact. The product is used for electrical pluggable elements.
Description
Technical field:
The utility model relates to a kind of appliance plug, and a kind of new type of safe of concrete design hangs down the arc plug.
Background technology:
The shortcoming of present plug technology, the number of times that produces electric arc is less than or equal to 1 time, the appliance plug technology is isometric electrode two contacts of contact base at the same time, two contacts can produce electric arc in succession, and the time of inserting also can prolong, and the number of times that promptly produces electric arc may be more than or equal to 2 times, and is higher to the damaged condition of electrical equipment, because the high temperature and the high light of electric arc have certain harm to electrical equipment and personnel.
Summary of the invention:
The low arc appliance plug of new type of safe can effectively reduce the generation of electric arc.
Above-mentioned purpose realizes by following technical scheme:
New type of safe hangs down the arc plug, and its composition comprises: described contact connects with grip portions, and the contact is bar-shaped or laminated structure at least two, the contact of bar-shaped or laminated structure wherein one length greater than other contact.
The new type of safe of the above hangs down the arc plug, and described contact one side has elastic device.
Described new type of safe hangs down the arc plug, and the length difference between the contact of two bar-shaped or laminated structures is at least 2 millimeters.
Described new type of safe hangs down the arc plug, and the space between the contact of bar-shaped or laminated structure and the adjacent shell is at least 0.5 millimeter.
The beneficial effects of the utility model:
The low arc appliance plug of new type of safe can effectively reduce the generation of electric arc.It has overcome the shortcoming of present plug technology, the number of times that produces electric arc is less than or equal to 1 time, and at present the appliance plug technology is isometric electrode two contacts of contact base at the same time, two contacts can produce electric arc in succession, and the time of inserting also can prolong, the number of times that promptly produces electric arc may be more than or equal to 2 times, and is higher to the damaged condition of electrical equipment.New type of safe hangs down the arc plug, the length that the above utmost point on two or two of plug is levied is made varying length, will when the plug place in circuit, keep a side at first to engage like this with circuit, avoid the both sides plug to form the generation of electric arc respectively and between the circuit, can effectively reduce the generation of electric arc, firm plug between plug and the socket, contact is good.Can effectively prolong the useful life of electrical equipment, electrical equipment is had good protective effect, prevent security incident.
This design is ingenious, simple in structure, with low cost, be easy to make, and is safe in utilization, convenient.Therefore, this product has bigger market potential.

Accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is this product internal structure schematic diagrames.
Embodiment:
Embodiment 1:
New type of safe hangs down the arc plug, and its composition comprises: described contact 1 connects with grip portions 2, and the contact is bar-shaped or laminated structure at least two, the contact of bar-shaped or laminated structure wherein one length greater than other contact.
The new type of safe of the above hangs down the arc plug, and described contact one side has elastic device 3, strengthens the rate of tension of pole piece, guarantees that pole piece is in tensioning state all the time.
Described new type of safe hangs down the arc plug, and the length difference between the contact of two bar-shaped or laminated structures is at least 2 millimeters, firm plug between plug and the socket, and contact is good.
